{\tt  {\tt FLCAT} {\em  start\_\-utc , stop\_\-utc, app\_\-id, out\_\-file } }

  \begin{TabularC}{2}
\hline
 start\_\-utc & The UTC time number of the first file to include.  \\\hline
 stop\_\-utc & The UTC time number of the last file to include.  \\\hline
 app\_\-id & The CCSDS App ID number to process.  \\\hline
 out\_\-file & The name of the output file. \\\hline

\hypertarget{description}{}\subsection{Description}\label{description}


The {\tt FLCAT} application concatenates output file sets from the {\tt FLPRSR} application into larger, more manageable files. The {\tt FLPRSR} program outputs file names of the form: \par


utc\_\-start.trx.app\_\-id \par


Where {\em $<$utc\_\-start$>$} is the UTC timestamp when file recording began on the TRX machine, and {\em $<$app\_\-id$>$} is CCSDS App ID stream number of the output. The  {\tt FLCAT} application joins all files between timestamps {\em start\_\-utc} and {\em stop\_\-utc} for a given {\em app\_\-id} stream.
